This invention relates to a fastening device, particularly applicable to women's garments, such as: dresses, coats, blouses, jackets, etc., bags, etc., characterised by the application of an 5 extensible jointed system, commonly called lazy I tongs, mounted so as to be capable of sliding along both edges of the opening, slide-blocks carried by the central pivots of said system bringing together and uniting the two opposite edges.

In the following will be described, by way of example, a form of construction of a device according to the invention. Reference will be made to the accompanying drawing, in which:

Fig. 1 is a front view.

Fig. 2 is a section made according to line 2--2 of Fig. 1.

Fig. 3 is a side view.

The parts of the garment .to be united together, for instance for the purpose of fastening them, are shown at l and 2. n the opposite edges of said parts are secured, for instance by stitching, braids 3 and 4 terminating in rolls 5 and 6. A socalled lazy tongs system. constituted by link members or blades -crossing' each other. and pivotally connected by central pivots 8 and end joints 9, so as to form two zigzags alternately overlapping each other, is secured, at one of its ends, I!) forinstance, atone end of the opening to be fastened.

The central pivots 8 are formed by rivets H on which are rotatably secured slide-blocks I! in the form of claws, the branches of which are capable of embracingthe rolls 5 and 6.

One of the ends of the jointed or pivoted system is secured to the garment.

The other end is free and carries an operating tassel l3, or the like.

The height of the slide-blocks I2 is, preferably, smaller than the widthof the blades I.

Fig. 1 shows a mean position of the pivoted system. when it is desired to further fasten the opening, the tassel I3 is pulled; the whole of the pivoted system distorts in the known manner, the'slide-blocks I2 sliding-along the rolls '5 and 6. The. edges of parts I and 2 spaced,

from each other are brought together and held one ag t the other by the action of the slideblocks 12 the shape of claws. For unfastening, it sufllces to pushback the tassel I 3.

The device according to the invention conseother hand, the slide-blocks being constantly, according to the properties of lazy tongs devices, arranged at an equal distance from each other, the fastening of the garment is always perfectly ensured whatever may be the degree to which 6' the pivoted system is extended; in particular, gaping cannot talie place.

In some cases, it may be advantageous to double every other one of the lazy tongs: distortions are thus avoided which might be pro- 10 duced in certain conditions of utilisation, without prejudice to the flexibility of the whole.

I not damaged by the friction of the blades one cnthe other'which is produced when fasteni and unfastening the device.

In some cases where it is advantageous to com- 30 pletely unfasten the garment, one of the rolls is so mounted as to be disengaged from the slideblocks, the device when it is completely unfastened or open being rigid with one only of the parts of the garment, the roll being re-inserted 25 in the slide-blocks for fastening.

What I claim as my invention and desire to secure by Letters Patent is:

1. A fastening device for 'bringingtogether and securing two opposite edges of garments, bags and flexible objects, comprising a series of alternately crossed link members pivotally connected at their adjacent ends so as to be extensible and retractible as a group and mutually 35 crossing 'along the longitudinal axis of. saidgroup, central pivot means connecting each pair of .link members at their points of crossing, and slidable fastening members individually carried by said central pivot means and cooperat- 4o ing'with and partly embracing the two opposite edges to be secured.

2. A fastening device for bringing together opposite edges of garments, bags and the like, comprising two series of 'link members pivotally secured at their ends to form two zigzags alternately overlapping each other and capable of expension and contraction to form parallelograms, the first and last blades of each series having half the length of the intermediate blades, each pair of first and last blades being pivotally secured at their free ends, central pivot means for securing the two series to each other at the overlapping portion of each pair of blades, and slidabie fastening members carried by said central 66 bracing opposite edges of an opening for bringing together and uniting said opposite edges.

'3. A fastening device as claimed in claim 1 wherein each of the slidable fastening members comprises a bridge member.

4. A fastening device as claimed in claim 1, wherein each of the slidable fastening members comprises a channel-shaped member.

5. A fastening device as claimed in claim 1, wherein each of the slidable fastening members comprises an inverted channel-shaped member, the central portion thereof being pivotally secured to the pivot means, the side portions of pivot means and cooperating with and partly em-' said channel-shaped member being turned inwardly towards each other.

6. A fastening device as claimed in claim 1,

- wherein one end of the series of link members is fixed against movement relative the opening to be closed.

'7. A fastening device as claimed in claim 1, wherein the edges of the fabric to be fastened have raised beads capable of being engaged and gripped by the slidable fastening members.

8. In a fastening device, as set forth in claim 1, said slidable fastening members being in the form of claws.
